PHP - Ob_start Before Session And Includes? Or After?

Hello,

   I am trying to change the string 'IRM Reporting Portal' to 'BIS Reporting Portal' as illustrated in the attachment 'Requirements.jpg'.

On inspecting 'IRM Reporting Portal', I noticed the function DoResizeMS ().

I found this function call in only one file across the entire code.

That file is 'header.dsp' (attached)

This leads me to believe that the string 'IRM Reporting Portal' is being dynamically generated in 'header.dsp' (Between ob_get_contents() and ob_start())

How do I change that string to 'BIS Reporting Portal'? Please help. I am a PHP newbie.

Thanks,
Trinanjan.

Hello, I am an absolute PHP newbie, and I have something which is probably a very stupid question. Nevertheless, I am stuck, despite Google and reading the docs.

Here a very cut down example code:
Code: [Select]
<?php
ob_start();
echo "123\n";
$body = ob_get_flush();
echo "body = ".$body;
?>
I would have expected the output to be
body = 123
It actually is
123
body=123
ie ob_start does indeed buffer the output, but it does not prevent if from getting through.
This happens both on my Mac with 5.3.10, and on my server where I dont know the PHP version (...newbie...)

Any help would be appreciated!

Hi,

this, i think, is a 'php in firefox' issue despite me mentioning css in the title so please read on!..

please have a look, using firefox, at http://www.laureleroch.com/gallery.php...

As you can see, when choosing different images via clicking on the thumbnails the page reloads and there's an amount of time where we see the page loaded without css applied..., however doesn't seem to be happening in IE9, opera, chrome, or safari. It IS happening in firefox on W7 and OSX.

the file gallery.php has...


<?php
session_start();
ob_start();
include("scripts/php/gallery_display.php");
include("scripts/php/file_reader.php");


...as its start...and...

 
</body>
</html>
<?php ob_flush() ?>

..at its end.

I can post all the code from the includes if required. I'd say there's a fair bit of processing done by these includes but really, not THAT much, plus other browsers seem to be doing ok with it.

Also, the background images are big. That's a fact. The site will be in this way and I plan to use a preloader once I get the main build sorted...nearly there.

One other thing...I really am a coding newbie. I've been toying with it for years, first with actionscript in flash, then html/css and now I'm getting really into php, however I'm sure my coding is pretty inefficient here and there thru nothing other than pure, undiluted ignorance...good, eh?!

so, if anyone got some pointers that would be really brilliant... any other info required - please shout.

cheers,

Scott

I am trying to use output buffering in the following manner:

Code: [Select]
ob_start("OB_BUFFER");
echo 'Start';
do_stuff_function();
ob_end_clean();
echo 'End';

The problem is that when the output of "do_stuff_function" exceeds 4k the output is automatically flushed and I don't know why (exceeding some limit I suppose). 

So when the output of "do_stuff_function" is less than 4k, I get this:

Code: [Select]
Start
My <4k output here...
End

When "do_stuff_function" exceeds 4k, I end up with this:

Code: [Select]
My > 4k output here...
Start
End

I don't understand why this is.  The docs seem to indicate that the way I am starting the ob_start() function there should be no buffer limit.  Is that not true?

Hi there,
I am trying to create a file using fwrite function, but for something reason all I get is a blank file with no content inside.
Here is the code, go to the bottom where the fwrite function is called:
<?php //Get Nohay Albums function

    }
        }

fclose ($cacheFile);
ob_flush();
ob_end_clean();

    }
}

GetAlbums("nauhey");
?>

When I execute the function, I get my self-made error "Cannot write cache content to file!". Help would be much appreciated. Thank you.

I am having trouble resolving an error.

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/s519970/public_html/header.php:27) in /home/s519970/public_html/admin/login.php on line 2

 What I can gather is I can't use "header (Location: 'admin.php')" after i've used session_start(). I have tried to replace the header (Location: 'admin.php') with this:

                echo "<script>document.location.href='admin.php'</script>";
      echo "<script>'Content-type: application/octet-stream'</script>";

I've been trying to read up on solutions but haven't been able to get it sorted. If anyone can offer some advice that would be greatly appreciated as im new to php.

Code: [Select]

I have tried using require_once('yourpage.php'); before my <head></head> tags in the header document where I've specified the html information but this doesn't seem to work. I've been advised to use ob_start("ob_gzhandler"); but I am not sure how to implement this.

Any advice is greatly appreciated!

Sorry for the long message but I need HELP!!!  I'm somewhat familiar with HTML but very little in PHP, and even less in CSS. My eCommerce program is PHP based so I've had to learn to work with it. I did have someone else initially setup and create my website but over the past few years have taken it further myself. I've fiddled with some of it and looked up how to do certain things, such as have only one header and/or sidebar I can use for all pages. I use Dreamweaver CS4 and FTP with FileZilla. But I'm still new at this and have run into a couple of issues.   My webhost is GoDaddy, my website is MikiCat Designs and after fiddling for months, in March finally got my site to where I liked it. Unfortunately, I haven't kept it up. Anyway, I went there a couple of weeks ago and found that the PHP includes I'd had in the HTML files were no longer working. I get the error [an error occurred while processing this directive]. Weird. Worked fine before, now it doesn't. Called GoDaddy who says they didn't do anything . Uh huh. Now I know I didn't do anything since I haven't updated the site in 4 months! So, what could have caused this problem?

I've had no idea how to fix it other than to change the index.html to index.php and, of course, do a minor repair on the include. Works fine and my header.php and leftsidebar.php show up again. Yay! Herein lies another problem.

My header and sidebar link to other files some of which were HTML files. But those HTML files had the same header and sidebar issues as my INDEX file. This had to be fixed so I changed them to PHP. Still working on the changes. I deleted most of the HTML files from the server.

So the links in my header and lefsidebar files now point to PHP files. e.g., gallery.html to gallery.php. When called on it's own, gallery.php shows up perfectly. But, no matter what I do, the header file still tries to load the HTML file!!! It's driving me crazy. What have I done wrong? I've deleted them both, refreshed, cleared cache and uploaded them again but I still get the same error. If you click on Gallery in the header, it tries to link gallery.html not gallery.php! Funny thing is, the leftsidebar now works perfectly and points to the proper PHP files. I'm completely confused now.

I don't know why my header is insisting on trying to load the HTML page instead of the PHP. But here's my header code. Lines 41 and 42 work, lines 43, 44 and 45 do not.   * Quietly banging head against wall while awaiting help.

Hi,

Im pretty much self taught when it comes to php, never read any books just picked things up as i go, and im looking for some advice on how i build my pages as i believe im not approaching it correctly.

Basically i build an index.php, this contains my header, footer, and any menus i may have, then for my content pages, in this case products, contact, about us i use use an include so these content pages just have content.

Now by doing this my address bar looks like this index.php?location=contact.php

for the sake of google and search results and so on, am i limiting my ability to be found by not using a differant file for each page? should i include a header, footer, menu etc within my content pages rather than the other way around?

Thanks in advance for any advice.

hi

This problem is the most strange thing that i seen in the last times.
this code works
Code: [Select]
<?php 
function conecta () {
$host = "localhost";
$senha = "vertrigo";
$login = "xxx";
$database = "emprego";
$conexao = mysql_connect($host,$login,$senha) or die(mysql_error());
mysql_select_db($database,$conexao)or die;
}

conecta ();

//more
?>
but this doesn't work
Code: [Select]
<?php 
require("includes/f_banco.php");
conecta ();

?>
I never seen something like that. Any ideia? the paths are correct, the bd is correct and the query works when i put the function conecta() directly in the php file.

Thanks

Ok, I am sure this is really simple for all of you, but I have very little experience with php. I haven't sat down to learn php yet, but I will when I have more free time. In the meantime I have the following issue:

The site is http://astoryaday.fromyay.com/

I have all the stories in the /stories/ directory, all named 20110504.html, 201105005.html, etc. Every day I write another story, I name it following that pattern, and drop it into the /stories/ folder.

I only want the newest story displayed on the page. So I wrote a little script that is:
Code: [Select]
<?php
$files = glob("stories/*.html");
sort($files);
$newest = array_pop($files);
include($newest);
?>
Now, what I want to do, is in the footer, put an Archive that will look like this:

-2012
--January
---03
---02
---01

-2011
--December
---31
---30

And upon clicking on the dates, the story from that day will replace the story that is currently included.

Any help of how to get this done would be appreciated!
Thanks

Hey everyone,

I am trying to secure php includes and I wrote the following lines:

Code: [Select]
<?php
$dir=scandir('.');

if (in_array('copyright.php',$dir)) {
include('copyright.php');
}
else {
echo 'That page could not be found';
}
?>

Is this code secure enough, can anyone help me improve it?

Thanks in advance.

I did some googling and it seems you cannot include a file with an anchor:

i.e include "hello.php#foo";

How do you guys go back to the middle of the page of an included file?  Do you just not include files with anchors?

I wanted to run my entire site inside index.php and just use includes to diplay the appropriate file, but I also need anchors to go to the middle of the page on some of those files.
